this Recipe

Ingredients:

• 4 large yellow onions, thinly sliced (about 5 pounds)
• 2 tablespoons olive oil
• 2 tablespoons butter, unsalted
• 1/2 teaspoon salt, plus more to taste
• 1/4 teaspoon black pepper, freshly ground, plus more to taste
• 1/4 cup balsamic vinegar
• 1/4 cup brown sugar, packed
• 1/4 cup dry red wine (optional, but recommended for depth of flavor)
• 2 tablespoons maple syrup (or honey)
• 1 teaspoon fresh thyme leaves (optional)
• 1/4 teaspoon smoked paprika (optional, for a smoky flavor)

Preparing the Onions: The Foundation of Flavor

Okay, let’s get started! The key to amazing caramelized onion jam is patience and low, slow cooking. Don’t rush this process; it’s where all the magic happens. We’re aiming for deeply golden, sweet, and incredibly flavorful onions.

1. Slice the Onions: First, peel your four large yellow onions. Then, using a sharp knife or a mandoline (be careful!), thinly slice them. Aim for slices that are about 1/8 inch thick. Uniformity is key for even cooking. If you’re using a knife, try to keep the slices consistent. Don’t worry too much about perfect slices; they’ll break down as they cook.
2. The Initial Sauté: In a large, heavy-bottomed pot or Dutch oven, heat the olive oil and butter over medium-low heat. The combination of oil and butter prevents the butter from burning and adds richness. Once the butter is melted, add all the sliced onions.
3. Season and Stir: Sprinkle the onions with 1/2 teaspoon of salt and 1/4 teaspoon of black pepper. The salt will help draw out moisture from the onions, which is crucial for the caramelization process. Stir the onions well to coat them evenly with the oil, butter, salt, and pepper.
4. The Long, Slow Cook: Now comes the patience part. Reduce the heat to low, cover the pot, and let the onions cook, stirring occasionally (about every 15-20 minutes), for about 1 to 1.5 hours. The goal is to cook the onions until they are very soft, translucent, and starting to turn a golden brown color.
5. Monitor and Adjust: During this initial cooking phase, keep an eye on the onions. If they start to stick to the bottom of the pot or brown too quickly, reduce the heat further. You might need to add a tablespoon or two of water or broth to the pot to prevent burning. The key is to maintain a low, gentle heat.

Caramelization and Flavor Infusion: Building Depth

Now that the onions are soft and translucent, it’s time to really caramelize them and infuse them with all those delicious flavors. This is where the magic truly happens, transforming simple onions into a gourmet jam.

6. Uncover and Caramelize: Remove the lid from the pot. Increase the heat slightly to medium-low. Continue to cook the onions, stirring frequently, for another 30-45 minutes, or until they are a deep golden brown color and very soft and jammy.
7. Stir, Stir, Stir: Stir the onions almost constantly during this phase to prevent them from burning. The sugars in the onions will start to caramelize, creating a beautiful color and a rich, sweet flavor. If the onions start to stick or burn, reduce the heat immediately.
8. Deglaze with Balsamic Vinegar: Once the onions are deeply caramelized, pour in the balsamic vinegar. The vinegar will deglaze the pot, lifting up any browned bits from the bottom and adding a tangy sweetness to the jam. Stir well to incorporate the vinegar into the onions.
9. Add Sweetness and Depth: Add the brown sugar, red wine (if using), and maple syrup (or honey) to the pot. Stir well to combine all the ingredients. The brown sugar will add a molasses-like sweetness, the red wine will add depth and complexity, and the maple syrup (or honey) will add a touch of natural sweetness.
10. Simmer and Thicken: Reduce the heat to low and let the jam simmer, uncovered, for another 15-20 minutes, or until it has thickened to your desired consistency. Stir occasionally to prevent sticking. The jam should be thick enough to coat the back of a spoon.
11. Add Optional Flavors: If you’re using thyme and smoked paprika, stir them into the jam during the last 5 minutes of cooking. The thyme will add a fresh, herbaceous note, and the smoked paprika will add a subtle smoky flavor.
12. Taste and Adjust: Taste the jam and adjust the seasoning as needed. You may want to add more salt, pepper, balsamic vinegar, or brown sugar to suit your taste. Remember that the flavors will intensify as the jam cools.

Finishing and Storing: Preserving the Goodness

Almost there! Now that your caramelized onion jam is perfectly cooked and seasoned, it’s time to finish it off and store it properly. This jam is incredibly versatile and can be used in so many ways, so you’ll want to make sure you have plenty on hand.

13. Cool and Store: Remove the pot from the heat and let the jam cool completely. As it cools, it will thicken further.
14. Transfer to Jars: Once the jam is cool, transfer it to clean, airtight jars or containers. You can use small mason jars for individual servings or larger jars for storing larger quantities.
15. Refrigerate: Store the caramelized onion jam in the refrigerator for up to 2 weeks.
16. Freezing (Optional): For longer storage, you can freeze the jam. Transfer it to freezer-safe containers, leaving some headspace for expansion. The jam can be frozen for up to 3 months. Thaw it in the refrigerator overnight before using.
